A 3-D Channel Model for High-Speed Railway Communications in Mountain Scenario
This paper proposes a novel three-dimensional (3-D) geometry-based stochastic channel model (GSCM) for high-speed railway (HSR) communications in mountain scenario. The proposed model not only takes the local scatterers into consideration, but also accounts for the effect of mountains on the wireless channel, which is not considered in existing models for HSR. The mathematical representation of the channel impulse response is given in this paper. Then the cumulative distribution function (CDF) of angle of departure (AoD) and space-time correlation function (STCF) are derived based on the proposed model. Finally, some numerical results and comparisons are given.
